CLAY-POT-IMAKING MACHINE.

Tofa ZZ it may concern Be it knownthat I, J OSEPH SCHUBERT, a United States, residin at James City, in the county of Elk and tate of Pennsylvania, have invented a new and of which the following is\a specification.

This invention has relation to machines for making clay pots and consists in the novel construction and ,arran ement of its parts as hereinafter shown an described.

The object machine of the character indicated which is of simple structure, the parts being so arranged that they may be readily manipulated in order to thoroughly compress the clay within the mold forming a component part of the machine.

core is located upon the frame and means is provided for raising andlowering the said the supporting rod of the core and means is rovided for reciprocating the said tamping devices. The said tamping devices are also so mo inted that they may be adjusted in order that they may operate close to the lower edges of the mold sections or adjacent the upper edges thereof according to the extent to which the said mold sections are filled with clay.

x -In the accompanying drawings:-Figure upper portion of the 7 is fixed to the lower end of the- 1 is a side elevation of the machine with parts broken away and parts in section. Fig. 2 is a vertical transverse sectional view of the inachinecut at a right angle to the view illustrated in Fig. 1.

The claypot making machine includes a foundation 1 upon which is mounted uprights 2 which constitute a superimposed frame. Mold sections 3' are hingedly connected together'and are hingedly connected with one of the uprights 2 of the frame of the machine.

The said mold sections 3 are provided at their forward edges with eyes 4 which are adapted to overlap and underlie each other and which when in alinement are adapted to receive a securing pin 5 as illus-- trated in Fig. 1 of the drawings.

A core rod 6 is slidably mounted in the frame of-the machine and a core said core rod. Said core 7 is adapted to lie between the sections Specification of Letters Patent.

J the frame of of the invention is to provide a I downwardly plate 14 and tamping gthe lower ends of the rods 15. With the above and other objects in view il l at the pp end of h 7 the machine includes a frame u'ponwhich is E hingedly mounted the-sections of a mold. ,A

Tamping devices are mounted upon ,the tamping 3 of the mold during the course of formation of the parts within Patentedduly 9, i912. Application filed August 15, 1910. Serial No. 577,300; I a

A cable 8 is attached at one end to the upper end of the core rod 6 and its intermediate portion is trained over sheaves. 9 and 10 which are journaled upon v The other or; lower end of the cable 8 is wound about the f periphery of the windin turn is journaled upon t5 A sleeve 121s slidably mounted uponthe machine.

drum n; which the intermediate portion of the core rod 6.3

and is provided with eyes 18.

t A lever 19 is iulcrumed upon one of the uprights 2 forming a component part of the 1 frame of the machine and is provided at one i end with prongs 20 which project through the eyes 18 of the head 17.

When a pot is being formed in the mold at which the sections 8 are components, sections 1 are closed together and their free edge portions are held in closed positions by means of pins 5 which pass through the alined eyes 4 of the said mold sections. The plunger 7 is then lowered into position be,- tween the mold sections 3 or the said plunger 7 is lowered into position after the bottom of the pot has been formed in the said mold section. The clay is then dropped between the periphery of the core 7 and the inner surfaces of the mold sections 3 and as the space between the said core and mold section is filled an operator swings the lever 19 which reciprocates the sleeve 12 along the core rod (3 and the tamping blocks 16 are moved and is provided with an external screwn ithread 13. A late 14 is internally threaded. and the threa in the said plate engages the thread .13 of the sleeve. Rods 15 extend from the edge portion of the blocks '16 are fixed to A head 17 is ,:i

said

vertically and upon their downward strokes they come in contact with the clay between the periphery oi the core 7 and the inner surfaces of the mold 3 and compress and form the same-about the core and within the said mold section; As the mold section 3" becomes filled with clay the plate 14 is rotated upon the sleeve 12 and inasmuch as the said sleeve is provided with a threaded opening which engages the threads 13 of the said sleeve 12, the plate is moved longitudinally along the said sleeve and consequently blocks 16 may be positioned so that they'will operate upon the clay toward thelower end of the mold section 3 or in the vicinity of the upper end thereof. In-

asmuch as the head 17 is journaled upon the upper end of the sleeve 12 it is not necessary todisconnect the prong 20 of the lever 19 y from the eyes 18 of the said head 17 in order to rotate the sleeve 12. Or if the head 17 is made integral with the sleeve 12 as some that during the formation of the sides of the pot in the mold sections and about the core 7 the sleeve 12 may be given a uniform reciprocatory movement and by adjusting the plate 14 upon the said sleeve the tamping block 6 will operate at the upper or lower edge portions of the mold sections as desired. After the pot has been formed between the mold sections, an operator vinds the cable 8 upon the drum 11 which raises the core rod 6 and the core 7 until the lower end of the said core is above the upper edge of the pot. The pin 5 is then removed from the eyes 4 carried by the mold section 3 and the free edge portions of the. said mold sections are swung apart when the pot may be lifted or moved from off of the platform 1.

By providing a machine of this character a pot may be formed in much less time than is now consumed in the formation of such articles inasmuch as the clay can he worked with much less Water in the same, and instead of making the pot in sections as is now the practice the entire pot may be formed at one operation which results in a saving c considerable time;

Having described the invention whatt claim as new and desire to secure byLettei-s Patent is In a device of the class described, a base; a frame secured to the base; a mold upon the base; a rod slidable in the frame; a core carried by the rod and adapted to move within the mold; an externally threaded sleeve slidable upon the rod; a plate threaded upon the sleeve, and independent of the frame; upright rods depending from the plate; tampers upon the upright rods,-
